Natalie McDonald, 34, and her seven-year-old niece, Valentina Foster, died after a house fire in Grangetown, near Middlesbrough, in the early hours of Wednesday, while Cleveland Police investigate the circumstances surrounding the blaze and have arrested two men on suspicion of murder.
Natalie's mother, Lisa Kirton, described her daughter as a “beautiful soul” who would have done anything for anyone. She said the 34-year-old was “lovely, bright and bubbly” and was loved by everyone who knew her.
Valentina, known to her family as Tina, had been staying with relatives during the school summer holidays. Her death has added to the grief surrounding the incident, which also left a 48-year-old woman critically ill in hospital and three other people with injuries that were not considered life-threatening.
Two men, aged 23 and 31, have been arrested on suspicion of murder and remain in police custody as detectives work to establish how the fire started and whether anyone else was involved.
Lisa Kirton said the loss of her daughter had left the family struggling to comprehend what had happened.

Describing Natalie as a “beautiful soul”, she said her daughter had been someone who was willing to help others and was “lovely, bright and bubbly”.
Kirton also spoke about the death of Valentina, describing her seven-year-old granddaughter as a “cute little kid” who had been spending the summer with her family.
She said the circumstances surrounding the deaths were particularly difficult for relatives to understand, adding that she could not believe a seven-year-old child had lost her life.
The family is now facing the loss of two relatives while investigators continue their work at the scene.
Natalie's 15-year-old daughter survived the fire after escaping from the property through an upstairs window, according to her grandmother.
Kirton said the teenager and a friend managed to get out after the friend kicked out a window, allowing them to escape.
She said the friend's actions had “saved their lives”.
The account provides an indication of the speed and danger of the fire, with those inside the property forced to find an alternative route to safety.
Emergency services attended the scene during the early hours of Wednesday, with the blaze causing serious damage to the property.
Cleveland Police said two men, aged 23 and 31, had been arrested on suspicion of murder. Both remained in police custody while detectives continued to investigate.
The force said it was keeping an open mind about the circumstances of the incident and could not rule out possible links to wider organised crime.
Police have not confirmed a motive and no conclusion has been reached about how the fire began.
Redcar and Cleveland Local Policing Commander Superintendent Emily Harrison said officers were working to establish exactly what had happened.
The force has increased patrols in the Grangetown area as part of efforts to reassure residents following the deaths.
Superintendent Harrison said police would maintain a high-visibility presence locally and encouraged anyone with concerns or information to speak to officers.
The deaths have shocked residents in Grangetown, where police are maintaining an increased presence while the investigation continues.
Detectives are expected to examine the circumstances leading up to the fire, the movements of those involved and any available evidence that could establish whether it was deliberately started.
The investigation comes as the wider area is already dealing with the aftermath of another fatal incident. The fire occurred about two miles from the scene of an A66 crash on Saturday morning in which five young men and two police officers were killed.
The proximity of the two incidents has heightened concern locally, although Cleveland Police have not established any connection between the house fire and the road collision.
Daily Dazzling Dawn understands that the investigation into the Grangetown deaths remains at an early stage. The arrests are an important part of the police inquiry, but they do not mean the suspects have been charged or found guilty of any offence.
For Natalie McDonald's family, however, the immediate focus remains on remembering a mother, daughter and relative described by those closest to her as caring and full of life, alongside seven-year-old Valentina, whose summer holiday with her family ended in tragedy.
Police continue to appeal for information as officers work to establish the full circumstances surrounding the fire and provide answers to the families of those affected.
